Canvas already offers familiar features like comments, where users can add suggestions or give more instructions for the AI model to follow when editing responses.
Canvas is still only available on the web version of ChatGPT for ChatGPT Plus, Teams, Enterprise and Edu users. Mac app users and anyone downloading the recently released Windows version of ChatGPT will have to wait until Canvas is rolled out to these standalone apps.
Currently, people can access Canvas on the regular ChatGPT window rather than in any custom GPTs.
